1. Background

The
Site Investigation Report and Alternatives Analysis Document (January 1996) and
the Sampling and Analysis Report (December 1995), both prepared by CH2M-Hill
under California Integrated Waste Management Board Contract C3060,
quantifies the possibility of hazardous materials and contamination at the Sand
City Dump Site. To date, the primary
contamination found at the site is low levels of lead contamination (TTLC
100-1500 ppm) in the refuse and burn ash layers of the dump. No other contaminants were identified as
significant in terms of frequency of occurrence or concentration levels with
respect to established regulatory action levels. The Board project engineer shall designate responsibilities for
segregation, testing, loading and transport of hazardous materials/hazardous
waste in the Board cleanup contractor and consultant’s work orders. The following document summarizes the
capabilities and procedures that will be available during the reconfiguration
project for identifying, segregating/handling, temporarily storing,
containerizing, labeling and transporting hazardous materials/hazardous
waste discovered during the
excavation process.

2. Procedures

A.
In the event that potentially hazardous containers or materials are discovered
during the excavation process, the following capabilities and procedures will
apply.

D.
All hazardous or potentially hazardous items shall be segregated and placed in
an on-site hazardous materials/hazardous
waste staging area. The staging area shall have a sand bag berm
(or other berm) and be lined with plastic. The following equipment shall be provided by the contractor at the
staging area:

Tarps
or similar covers will be available for covering the staging area and
protecting it from the elements (sufficient circulation will be provided to prevent any
fumes or vapors from
accumulating).

2
EA portable fire extinguishers (C02 or Halon).

A
temporary construction fence shall be used around the staging area and signage
shall be placed. If an item cannot be
stored temporarily on-site, the Monterey Regional Waste Management District
(Marina Landfill), has agreed to temporarily stage hazardous containers,
batteries or other material classified as hazardous (except burn-ash and
contaminated soil) in the Marina Landfill hazardous waste storage area. Appropriate hazardous waste manifests shall
be required and a registered hauler shall be used.

E.
Items in the staging area shall have HAZCAT tests performed by the hazardous materials/hazardous
waste subconsultant. These screening tests may include: color, phase, odor, ignitability, density, specific gravity, pH, water reactivity, solubility,
percent solids, oxidizer, halogenated compounds, heavy metals (Cd, Ni, Cr+3,
Cr+6,
Ag, Zn, Pb). If screening shows
the need for further quantification, samples shall be taken and sent to a State
Certified Laboratory for analysis. Appropriate sample handling and chain-of-custody procedures shall be
followed.

F. If HAZCAT screening indicates that any items are chemically incompatible,
they shall be appropriately segregated in the staging
area to ensure that commingling of incompatible materials does
not occur. Appropriate isle space shall
be maintained to ensure
hazardous items may be accessed.

G. Once hazardous items are appropriately identified they shall be properly
packaged, containerized or over packed as necessary. For free liquids identified
as petroleum products, material may be pumped into a bowser or other bulk
container, including tank trucks.

H.
Once hazardous items are appropriately contained or packaged they
shall be labeled, placarded or marked with standard Department of
Transportation nomenclature per 49 Code of Federal Regulations (CFR).

I.
Uniform hazardous waste manifests shall be completed for all items
requiring disposition to a class I disposal facility.

The hazardous materials/hazardous
waste subconsultant shall be responsible for obtaining a temporary generator’s
US EPA identification number for the uniform hazardous waste manifest. This person shall be issued a letter of authorization signed by the
Board program manager authorizing him/her
to sign the generator’s certification in block 16 of the manifest. The letter
of authorization shall specify the name of the individual authorized, his/her
title, employer, and project location:

Call the Department of Toxic Substances Control at (800) 618-6942
for a temporary identification number good for 90 days for that site.

Call the State Board of Equalization Account Registration Unit at (916)
322-9534 for a hazardous waste tax account number.

Use the following as the generator’s name, mailing address and phone number in
blocks 3 and 4 of the manifest:

The letter of authorization shall be retained in the Board’s project files and
the consultant’s files. It is not necessary to attach a copy of the letter to
the manifest.

When site construction management is performed by Board project engineer, the engineer shall perform the above procedures.

After site cleanup and completion of manifesting, the hazardous waste tax
account shall be closed out by the hazardous materials/hazardous
waste subconsultant.

J.
Upon completion of the project and removal of all hazardous materials/hazardous
waste from the site, the contractor shall remove the
temporary hazardous materials/hazardous
waste staging area and dispose of or reuse materials as appropriate.
